I received my PhD from Nottingham University in 1986 and held a series of postdoctoral fellowships at the University of Liverpool until 1995 when I moved to UWA. I received an ARC Federation Fellowship in 2004 and was elected to the Australian Academy in 2009. I am Editor of Advances in the Study of Behavior, and a Research Adjunct at the Western Australian Museum.

My research uses both vertebrates and invertebrates to test the predictions and assumptions of theoretical models of sexual selection and life history evolution.

Research in my lab is focussed on five areas: i) sperm competition and paternal effects mediated via seminal fluid; ii) the evolution of animal genitalia; iii) natural and sexual selection acting on insect cuticular lipids; and iv) the effects of diet on reproductive health; v) the potential for sexual selection to promote population fitness. Collectively, these research programs seek to determine the direction and strength of selection acting on male and female reproductive strategies, and on the morphological and life history traits that contribute to fitness, from the whole organism to its gametes. My lab currently hosts collaborative research programs involving 4 PhD students and 2 postdoctoral researchers, and has hosted research fellows from Sweden, Finland, Spain, Switzerland, the US and the UK.

Opportunities are available for researchers at all levels, and I encourage interested individuals to contact me directly.
